Chapter 2 — Getting to Know the Personal Tracker

Positioning the Personal Tracker

8
The Personal Tracker uses both GPS and Iridium satellites. It is important that it
has the best possible clear sky view at all times in order to ensure good satellite
coverage. Positioning the Personal Tracker in a high upright position (vertically)
with a clear line of sight to the sky ensures the best connection. The line of sight
obstruction of Iridium satellites should be avoided where possible (such as by
buildings, dense trees, vehicles, etc.).
The tracker is best used with it's own fitted antenna, however, if used in a
shielded area (for example in a vehicle), an external antenna can be used (see
"Using a Remote Antenna" on page
Remember the following:
• Give the Personal Tracker the best view of the sky whenever possible.
• Locate the Personal Tracker at the highest possible position, free from
obstructions and safe from damage.
• Tracker performance is best when the antenna is placed vertically.
Horizontal orientation will affect antenna performance for both GPS and
Iridium satellite.
• Nearby radar transmitters, other satellite communications equipment and
microwave dishes may affect the performance of the Personal Tracker.
• Keep the Personal Tracker as far as possible from other electrical/electronic
devices in order to minimize interference.
• Do not position on hot surfaces.
• Regularly review the Personal Tracker's coverage by checking the signal
strength icons, and ensuring that any messages that you have sent are
moving from the Outbox to the Sent mailbox (see
page 21).
Note: The Iridium constellation is constantly moving and it is normal for your
tracker to go in and out of coverage.
